During a phase change, the temperature of a substance ____

Chemistry
1 answer:
Katen [24]3 years ago
5 0

Answer:

During a phase change, the temperature of a substance remains constant

Explanation:

Step 1:

During phase change, the energy that is required, will be used to separate the molecules ( to change phase).

This energy is not used to change the temperature.

Since the kinetic energy of the molecules remains the same, the temperature of the substance remains constant.

What is the molar mass of magnesium carbonate, MgCO3? 52.314 g/mol 84.313 g/mol 96.771 g/mol 102.588 g/mol
Orlov [11]

Answer:

Molar mass of MgCO3 = 84.3 g/mol

Explanation:

What is the molar mass of magnesium carbonate.

Molar mass of a substance is defined as the mass of one mole of the substance expressed in grams hence its unit is gram per mole (g/mol)

MgCO3 is a compound and it's molar mass would be the sum of the molar masses of the elements that make up the compound. MgCO3 contains 1 atom of magnesium, one atom of carbon and 3 atoms of oxygen

Molar mass of Magnesium = 24.3g

Molar mass of Carbon =12g

Molar mass of Oxygen = 16g

Molar mass of MgCO3 will be

24.3 + 12 + 16×3

= 24.3 + 12 +48 = 84.3 g/mol

Molar mass of MgCO3 = 84.3 g/mol

What are the chemical properties of CO2<br>​
Irina-Kira [14]

Answer:

Carbon dioxide is a linear covalent molecule.

Carbon dioxide is an acidic oxide and reacts with water to give carbonic acid.

CO 2 + H2O ==> H2CO3

Carbon dioxide reacts with alkalis to give carbonates and bicarbonates.

CO 2 + NaOH ==> NaHCO3 (Sodium BiCarbonate )

NaHCO3 + NaOH ==> Na2CO3 (Sodium Carbonate) + H2O
